Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicles, in particular to a mounting bracket and a vehicle. Background Art

[0002] With the rapid development of new energy vehicle technology, new energy vehicles have become the mainstream models in the modern transportation field. As the core of vehicle energy storage, the battery pack is usually carried and fixed by a dedicated mounting bracket. Currently, the industry generally uses welding or roll forming processes to manufacture the mounting bracket, and its cross-sectional structure is mostly designed as a "square" or "eye" configuration. Such structures exhibit good mechanical properties when resisting normal loads perpendicular to the surface of the mounting bracket. However, under the actual driving conditions of the vehicle, the mounting bracket needs to withstand multi-directional composite impact loads (such as longitudinal vibration, lateral torsion, and axial extrusion, etc.). In such complex stress scenarios, the structure of the traditional "square" or "eye" cross-sectional mounting bracket is prone to deformation, affecting the overall stability and safety of the battery pack. Summary of the Utility Model

[0003] This application provides a mounting bracket and a vehicle, and the bearing capacity and stability of the mounting bracket are relatively high.

[0004] This application provides a mounting bracket, which includes: a body having a receiving cavity; at least two support walls located in the receiving cavity, and both ends of the support walls are respectively connected to two opposite side walls of the receiving cavity, and the support walls divide the receiving cavity into at least three cavities; at least part of the support walls are inclined.

[0005] In this solution, the support walls located in the receiving cavity of the body abut against the two side walls of the receiving cavity, and the support walls play a strengthening role. When the mounting bracket is subjected to an external load, the support walls can play a role in transmitting the load, thereby transmitting the impact load received by the mounting bracket to multiple support surfaces, improving the anti-impact performance of the mounting bracket. In addition, multiple support walls can change the cross-sectional shape of the mounting bracket, thereby increasing the sectional moment of inertia of the mounting bracket and improving the flexural rigidity of the mounting bracket. And the inclined support walls can make the load be transmitted along the inclined support walls when compressed, thereby reducing the load transmitted to the side walls of the body and further improving the anti-impact performance of the mounting bracket. And the support walls divide the receiving cavity into at least three cavities, and each cavity forms an independent air flow channel, which can improve the heat dissipation efficiency of the mounting bracket and reduce the weight of the mounting bracket, thereby helping to reduce the overall weight of the vehicle.

[0006] In a possible design, the inclination directions of at least two of the support walls are opposite.

[0007] In this design, the two inclined support walls can decompose the external load into horizontal and vertical components. When the two support walls are inclined in opposite directions, the horizontal component forces on the two side walls are in opposite directions, which reduces the risk of damage to the side walls when subjected to impact loads and improves the structural strength of the side walls of the main body.

[0008] In one possible design, the receiving cavity has a first sidewall and a second sidewall disposed opposite to each other along a first direction, and the two ends of the support wall are respectively connected to the first sidewall and the second sidewall; the support wall includes at least a first support wall and a second support wall with opposite inclination directions, and the angle between the first support wall and the first sidewall is α, and the angle between the second support wall and the first sidewall is β, where α=β.

[0009] In this design, the first support wall and the second support wall are connected to the first side wall and the second side wall, respectively, to support the first side wall and the second side wall and improve their strength. The first support wall and the second support wall are inclined in opposite directions and have the same angle with the first side wall. At this time, the first support wall, the second support wall and the first side wall form a relatively stable isosceles trapezoidal structure, which can effectively improve the strength and rigidity of the mounting frame. The symmetrical angle design makes the load evenly distributed along the support wall, avoids stress concentration on one side, and improves the service life of the mounting frame.

[0010] In one possible design, the included angle α between the first support wall and the first side wall satisfies 45°≤α≤75°; and the included angle β between the second support wall and the first side wall satisfies 45°≤β≤75°.

[0011] In this design, when the angle between α and β is too large, the first and second support walls tend to be perpendicular to the first side wall, and the cavity they form is nearly rectangular. This weakens their ability to bear external loads along the second direction z, making the mounting frame prone to deformation under external forces along the second direction z. When α and β are too small, the ability of the first and second support walls to withstand external loads along the first direction x is weakened, making the mounting frame prone to deformation under external forces along the first direction x. Furthermore, a large angle increases the length of the support walls, raising manufacturing costs. In this design, when 45°≤α≤75° and 45°≤β≤75°, the support walls not only have sufficient resistance to external loads along both the first and second directions x, improving the stability of the mounting frame, but also save materials and reduce costs.

[0012] In one possible design, the mounting bracket further includes a connecting portion located within the receiving cavity, the connecting portion connecting to an adjacent support wall, the connecting portion and the adjacent support wall connected thereto forming a zigzag structure, and the connecting portion connecting to a side wall of the receiving cavity.

[0013] In this design, the connecting part is located within the receiving cavity and connects the first and second support walls to form a U-shaped structure. The symmetrical U-shaped structure provides good stability and can distribute external loads to the side walls, improving the strength and rigidity of the mounting frame. Furthermore, the first and second support walls are connected to the first side wall via the connecting part, which has a large contact area with the first side wall, effectively dispersing the force on the first side wall, reducing stress concentration, and further enhancing the strength of the mounting frame.

[0014] In one possible design, the body has a plurality of first mounting holes extending through the mounting bracket along a second direction.

[0015] In this design, a bolt is used to secure the mounting bracket to the vehicle body via a first mounting hole. The bolt passes through the first mounting hole, limiting the displacement of the mounting bracket and ensuring a secure and reliable connection between the mounting bracket and the vehicle body. This design not only improves installation efficiency but also facilitates later maintenance and adjustments. Furthermore, the preload of the bolts enhances the overall structure's vibration resistance and extends its service life.

[0016] In one possible design, the mounting bracket further includes a mounting slot and a second mounting hole.

[0017] In this design, the mounting slot is used to engage with the battery pack for positioning, and a locking mechanism is used to secure the mounting bracket to the battery pack via the second mounting hole. The mounting slot design simplifies the installation and positioning of the battery pack and mounting bracket when combined, and the locking mechanism via the second mounting hole further enhances the installation reliability of the mounting bracket and battery pack.

[0018] In one possible design, the body and the support wall are integrally formed by roll forming.

[0019] In this design, the main body and support wall are integrally formed using roll forming, resulting in high material utilization and reducing cost increases caused by material waste during production. Furthermore, the integral forming of the main body and support wall eliminates cumulative errors and improves production accuracy during the manufacturing of the mounting frame.

[0020] In one possible design, the receiving cavity has a first sidewall and a second sidewall disposed opposite to each other along a first direction, the second sidewall comprising a first segment and a second segment, the first segment being integrally formed with a support wall, and the second segment being welded to the support wall and the first segment.

[0021] In this design, the first section of the second sidewall is integrally formed with the first support wall. Referring to the figure, there is a significant angle change at the connection between the first section and the first support wall. Integral forming ensures a seamless connection, continuous stress distribution, and improved strength. Furthermore, the second section is welded to both the first section and the second support wall, eliminating gaps in the integral roll forming process and enhancing the mounting frame's resistance to deformation. The welding at two locations ensures that even if one location experiences failure or wear, the other location maintains the stability of the mounting frame structure, improving its stability during use.

[0046] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0047] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0049] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0050] In automobile manufacturing, battery packs are mounted on mounting frames, and the structural strength and stability of these mounting frames are closely related to vehicle safety.

[0051] The vehicle in this embodiment includes a body, a battery pack, and a mounting bracket 1. The battery pack is mounted on the vehicle body via the mounting bracket 1.

[0052] like Figure 1 As shown, the mounting bracket 1 includes a body 11 and a support wall 12. The body 11 forms a receiving cavity 111. The support wall 12 is located inside the receiving cavity 111, and the two ends of the support wall 12 abut against the two opposite side walls of the receiving cavity 111. The support wall 12 divides the receiving cavity 111 into at least three cavities, and at least part of the support wall 12 is inclined inside the receiving cavity 111.

[0053] In this embodiment, the support wall 12 located within the receiving cavity 111 of the main body 11 abuts against the two side walls of the receiving cavity 111. The support wall 12 serves a reinforcing function, enabling the mounting bracket 1 to transfer the load when subjected to external loads, thereby distributing the impact load on the mounting bracket 1 to multiple support surfaces and improving the impact resistance of the mounting bracket 1. Furthermore, the multiple support walls can alter the cross-sectional shape of the mounting bracket, thereby increasing the moment of inertia of the mounting bracket and improving its bending stiffness. The inclined support wall 12 allows the load to be transferred along the inclined support wall under pressure, reducing the load transmitted to the side walls of the main body and further improving the impact resistance of the mounting bracket. Moreover, the support wall 12 divides the receiving cavity 111 into at least three chambers, each forming an independent airflow channel, which can improve the heat dissipation efficiency of the mounting bracket 1 and reduce its weight, thus contributing to a reduction in the overall weight of the vehicle.

[0054] In one specific embodiment, such as Figure 1 As shown, the two support walls 12 of the mounting bracket 1 are tilted in opposite directions.

[0055] In this embodiment, the two inclined support walls 12 can decompose the external load into horizontal and vertical components. When the two support walls are inclined in opposite directions, the horizontal component forces on the two side walls are in opposite directions, which reduces the risk of damage to the side walls when subjected to impact loads and improves the structural strength of the side walls of the body.

[0056] In one specific embodiment, such as Figure 2 As shown, the cavity 111 has a first sidewall 112 and a second sidewall 113 arranged opposite to each other along the first direction x. The two ends of the support wall 12 are respectively connected to the first sidewall 112 and the second sidewall 113. The support wall 12 includes a first support wall 121 and a second support wall 122 with opposite inclination directions, and the included angle α between the first support wall 121 and the first sidewall 112 is equal to the included angle β between the second support wall 122 and the first sidewall 112.

[0057] In this embodiment, the first support wall 121 and the second support wall 122 are respectively connected to the first side wall 112 and the second side wall 113 to support the first side wall 112 and the second side wall 113, thereby improving the strength of the first side wall 112 and the second side wall 113. The first support wall 121 and the second support wall 122 are inclined in opposite directions and have the same angle with the first side wall 112. At this time, the first support wall 121, the second support wall 122 and the first side wall 112 form a relatively stable isosceles trapezoidal structure, which can effectively improve the strength and rigidity of the mounting frame 1. The symmetrical angle design makes the load evenly distributed along the support wall 12, avoiding stress concentration on one side and improving the service life of the mounting frame 1.

[0058] Specifically, the included angle α between the first supporting wall 121 and the first side wall 112 satisfies 45°≤α≤75°. For example, the angle α can be: 50°, 55°, 60°, 65°, 66°, or 70°.

[0059] The included angle β between the second supporting wall 122 and the first side wall 112 satisfies 45°≤β≤45°. For example, the angle β can be: 50°, 55°, 60°, 65°, 66°, or 70°.

[0060] In this embodiment, when the angle between α and β is too large, the first support wall 121 and the second support wall 122 tend to be perpendicular to the first side wall 112, and the cavity they form is close to a rectangle. This weakens their ability to bear external loads along the second direction z, making the mounting frame 1 prone to deformation under external forces along the second direction z. When α and β are too small, the ability of the first support wall 121 and the second support wall 122 to withstand external loads along the first direction x is weakened, making the mounting frame 1 prone to deformation under external forces along the first direction x. Furthermore, a large angle increases the length of the support wall 12, increasing manufacturing costs. In this solution, when 45°≤α≤75° and 45°≤β≤75°, not only does the support wall 12 have sufficient resistance to external loads along both the first direction x and the second direction z, improving the stability of the mounting frame 1, but it also saves materials and reduces costs.

[0061] In one specific embodiment, such as Figure 2 As shown, the mounting bracket 1 also includes a connecting portion 123 located in the receiving cavity 111. The connecting portion 123 is used to connect the adjacent first support wall 121 and the second support wall 122. The connecting portion 123 and the first support wall 121 and the second support wall 122 connected thereto form a zigzag structure. The connecting portion 123 also abuts against the first side wall 112 of the receiving cavity 111.

[0062] In this embodiment, the connecting part 123 is located within the receiving cavity 111 and connects the first support wall 121 and the second support wall 122 to form a U-shaped structure. The symmetrical U-shaped structure has good stability and can distribute external loads to the side walls, improving the strength and rigidity of the mounting frame 1. Furthermore, the first support wall 121 and the second support wall 122 are connected to the first side wall 112 through the connecting part 123. The large contact area between the connecting part 123 and the first side wall 112 can disperse the force on the first side wall 112, reduce stress concentration, and improve the strength of the mounting frame 1.

[0063] In the above embodiments, the body 11 and support wall 12 of the mounting frame 1 are integrally roll-formed, resulting in uniform material distribution and a stable structure. The use of integral roll forming ensures high material utilization and reduces cost increases caused by material waste during production. Furthermore, the integral forming of the body 11 and support wall 12 eliminates accumulated errors and improves production accuracy during the manufacturing of the mounting frame 1.

[0064] In one specific embodiment, such as Figure 2 As shown, the receiving cavity 111 has a first sidewall 112 and a second sidewall 113 arranged opposite to each other along the first direction x. The second sidewall 113 includes a first section 1131 and a second section 1132. The first section 1131 is integrally formed with the first support wall 121, and the second section 1132 is welded to the first section 1131 and the second support wall 122 respectively.

[0065] In this embodiment, the first segment 1131 of the second sidewall 113 is integrally formed with the first support wall 121, as shown in the reference. Figure 2 The first segment 1131 has a significant angle change at its connection with the first support wall 121. The integral molding process ensures a seamless connection between the first segment 1131 and the first support wall 121, maintaining a continuous stress state and improving the strength of the connection. Furthermore, the second segment 1132 is welded to both the first segment 1131 and the second support wall 122, fixing any gaps or lack of support after integral roll forming and improving the mounting frame 1's resistance to deformation. The welding at two locations ensures that even if one location experiences failure or wear, the other location maintains the structural stability of the mounting frame 1, enhancing its stability during use.

[0066] In the roll forming of the mounting frame 1, the structural parts are formed sequentially in the following order: first, the second support wall 122 is formed, followed by roll forming of the connecting part 123; then, the first support wall 121, the first section 1131, the third side wall 117, the first side wall 112, and the fourth side wall 118 are formed in sequence, and finally, the roll forming of the second section 1132 is completed. After roll forming, the first section and the second section are welded together to form the mounting frame.

[0067] In one specific embodiment, such as Figure 3 As shown, the body 11 has a plurality of first mounting holes 115, and the first mounting holes 115 penetrate the body 11.

[0068] In this embodiment, a fastener, which can be a bolt, secures the mounting bracket 1 to the vehicle body via the first mounting hole 115. The bolt passes through the first mounting hole 115, limiting the displacement of the mounting bracket 1 and ensuring a stable and reliable connection between the mounting bracket 1 and the vehicle body. This solution not only improves installation efficiency but also facilitates subsequent maintenance and adjustment. Furthermore, the preload of the bolts enhances the overall structure's vibration resistance and extends its service life.

[0069] In one specific embodiment, such as Figure 1 , Figure 3 As shown, the mounting bracket 1 also includes a mounting groove 114 and a second mounting hole 116.

[0070] In this embodiment, the mounting slot 114 is used for positioning and engaging with the battery pack, and a locking member is used to lock the mounting bracket 1 and the battery pack through the second mounting hole 116. The locking member can be a long screw. The design of the mounting slot 114 makes the installation and positioning of the battery pack and the mounting bracket 1 simple when combined, and the locking through the second mounting hole 116 further improves the installation reliability of the mounting bracket 1 and the battery pack.

[0071] In one specific embodiment, the battery pack has a long T-shaped strip, and the long T-shaped groove is embedded into the mounting bracket 1 through the mounting groove 114. After the long T-shaped strip is embedded into the mounting bracket 1, a locking member is used to fix the T-shaped strip on the mounting bracket 1 through the second mounting hole 116, thereby fixing the long T-shaped strip.

[0072] In addition, it should be noted that the first mounting hole 115, the second mounting hole 116 and the mounting groove 114 are all formed before roll forming, that is, the metal plate to be rolled is provided with the first mounting hole 115, the second mounting hole 116 and the mounting groove 114.

[0073] The above descriptions are merely specific implementations of the embodiments of this application, but the protection scope of the embodiments of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the embodiments of this application should be covered within the protection scope of the embodiments of this application. Therefore, the protection scope of the embodiments of this application should be determined by the protection scope of the claims.
